Dynamic Airport Moving Map Display Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flight deck displays do not account for aircraft groundspeed when displaying airport features, leading to inadequate situational awareness for pilots during taxi operations and final approach, as critical features like runway and taxiway signs fade in at a fixed distance regardless of the aircraft's speed.
Innovation Solution
A method and system that dynamically adjust the depth of field in a three-dimensional airport moving map display based on the aircraft's speed, rendering airport features at a greater distance as the aircraft exceeds a predetermined speed, enhancing the timeliness and quality of displayed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If airport features are displayed at a fixed distance from the aircraft, then the display system is simple to operate, but the pilot's situational awareness is inadequate during high-speed taxi operations
Solution Approach 1:
The display system dynamically adjusts the fade-in distance of airport features based on aircraft groundspeed. When the aircraft exceeds a predetermined speed threshold, the system automatically extends the distance at which features such as runway and taxiway signs begin to fade into view, ensuring timely visibility without requiring complex manual configuration
Solution Approach 2:
The system changes the display parameter of fade-in distance according to aircraft speed conditions. By monitoring groundspeed and adjusting the display distance parameter accordingly, the system optimizes information visibility for different operational phases without adding significant complexity to the display architecture
2Loss of time
If airport features fade in at a fixed distance, then the display system is easy to implement, but critical features are not displayed timely during high-speed operations
Solution Approach 1:
The system performs preliminary action by extending the fade-in distance of airport features before the aircraft reaches high speed. By anticipating the speed increase and pre-adjusting the display parameters, the system ensures that critical features become visible in advance, providing pilots with adequate reaction time
Solution Approach 2:
The display system continuously monitors aircraft groundspeed and uses this feedback to automatically adjust the fade-in distance of airport features. This closed-loop control ensures that the display remains optimized for current flight conditions without requiring complex manual intervention
3Loss of information
If the depth of field is increased for high-speed display, then situational awareness improves, but the display system becomes more complex
Solution Approach 1:
The system implements dynamic adjustment of field depth by extending the display distance for airport features when aircraft speed exceeds a predetermined threshold. This automatic adaptation provides enhanced situational awareness during high-speed operations while maintaining simplicity during low-speed taxiing
Solution Approach 2:
The display system changes the field depth parameter based on aircraft speed conditions. By automatically adjusting this parameter rather than requiring manual configuration, the system achieves improved information visibility without proportionally increasing operational complexity

AI summary
A method and apparatus is provided for enhancing situational awareness onboard an aircraft during an aircraft ground maneuver such as when taxiing on a runway or taxiway. A three-dimensional view including airport features is rendered in a first airport region that extends a first predetermined distance (D1) from the aircraft when the aircraft speed is less than a predetermined speed (V1). A three-dimensional view including airport features in a second airport region is rendered that extends beyond D1 when the aircraft speed exceeds V1.
